Detailed report: Why LME approved Hong Kong warehouses over Mainland China

In a recent development for the London Metal Exchange’s (LME’s) Asian strategy, the announcement of its approval of the first four warehouse facilities in Hong Kong in April 2025 floated in the trading market. These newly approved warehouses, operated by a trio of company pairs, are slated to commence storing LME-warranted metal within three months of the announcement. This expansion marks a notable step for the LME, particularly considering its acquisition by Hong Kong Exchanges and Clearing (HKEX) in 2012.

The central question that arises from this decision is why the LME, who facilitate trillions of dollars in transactions annually across numerous approved metals, including aluminium, copper, and zinc, chose Hong Kong, a territory acknowledged to have limited local consumption of industrial metals, over Mainland China. This query is particularly pertinent given that Mainland China is the world’s largest consumer and trader of a vast range of metals. This apparent contradiction necessitates a detailed examination of the factors influencing the LME’s strategic choice.

The speed at which the warehouse facilities were approved, merely months after the location itself received the green light, suggests a well-coordinated plan and a strong impetus behind this expansion. Furthermore, statements from the LME and HKEX consistently highlight Hong Kong’s role as a ‘gateway to Mainland China’. This recurring emphasis implies that while establishing direct warehousing facilities within Mainland China might present considerable challenges, Hong Kong is perceived as a vital strategic alternative for indirectly serving the expansive Chinese market.
